To (LZZ @07mm t may concern.'

Be it known that I, HERMANN VVARTEN- BERG, a citizen of the German Republic, residing at Charlottenburg, near Berlin, Germany, have invented certain new and useful Improvements in Explosion Engines, of which the following is a specification.

My invention relates to explosion engines or socalled internal combustion engines, and in particular to a device for keeping the cooling water required by such engine constantly at a certain temperature.

lhe object of my invention, therefore, is

to provide a simple and ehcient means for' automatically regulating the temperature of the water supplied to the engine for cooling purposes. l

l/Vith this object in view the invention consists of certain novel features of construction comprising mainly a spring-controlled valve in a casing adapted to be inserted in the cooling water conduit of an explosion engine, and a socalled thermostatic tube connected with said valve in a manner to control the passage through said casing in accordance with the fall and rise of the temperature of the water flowing through the said conduit.

Further objects and advantages of my invention will be set forth in the detailed description which now follows. f

In the accompanying drawings; Figure l represents a vertical section through the casing containing the spring-controlled valve and the thermostatio regulating inember; Figure 2 is a similar sectional view of a modification embodying means for setting and adjusting' both the controlling spring and the thermostatic member; Figure 3 is a sectional view on an enlarged scale according to line A-B of Figure 2.

Referring to the embodiment sho-wn in Fig. l a designates the casing with an inlet b and an outlet c adapted to be inserted in the cooling waterconduit of the engine. A partition wall d is provided in the casing so that two separate rooms c and f are formed therein. A cook g is provided in the wall of the casing for emptying purposes.

The partition Z is out out to form a seat for a valve 7L which is loosely mounted on a fixed rod i, that is to say, so as to be displaceablethereon in an axial direction. The two threaded ends of the rod z' are mounted each in a spider or the like lc and Z, respectively, and nuts are employed for setting and fixing the rod therein as clearly shown in the drawing. The valve it is under the control of a. spring mi, constantly acting to press the same into its seat in the partition'rZ.

A thermostatic tube n is mounted on the rod z' in the following manner. The upper end of the tube carries a sleeve o and the lower end thereof carries a disk or rin p, both the sleeve and the ring being rigidly connected with the tube, which preferably has a circular shape. The ring p and the sleeve o loosely enga-ge the rod z', but the sleeve o is set to cause the ring p to' abut against the valve h which, as above stated, likewise is axially displaceable on the rod z'. In the wall of the sleeve a small screw is provided for fixing the sleeve and the tube n in the set or adjusted position on the rod z'. 1i

From the above description it will be seen that the thermostatic tube n. is intended to counteract the action of the spring m in order to lift the valve from its seat and to allow cooling liquid to pass through the outlet o to an amount depending upon the throw of the thermostatic tube a..

In the modification shown in Figures 2 and 8 the very same principle is embodied, that is to say, a valve is provided therein which is controlled by a thermostatic tube to keep the temperature of the cooling water to be supplied to the engine, at a certain height; to ensure the best cooling effect in the engine.

In the embodiment illustrated in Figures 2 and 3 means are provided for setting or adjusting the controlling spring m of the valve from the outside of the casing. To this end a rod or shaft g is mounted in a suitable bearing g integral with the casing ct and a cam or arm 71 is firmly connected with the inner end of said shaft Q so as to engage the flange s of a sleeve t. The latter is loosely mounted on the rod 'z' and the valve controlling spring m is disposed on the rod zso as to abut with its one end against the valve It and with its other end against the said sleeve t.

The outer end of the shaft g, Figure 3, is shaped to form a collar u adapted Ato be embedded in a correspondingly shaped re.- eess of the bearing g. A disk o surroundthermostatic tube n and the il l) ail ing the projecting end of the shaft g is provided for the purpose of frictionally tixing the collar Iu Within the said recess by means of screws w, after the spring m has been duly set or adjusted by turning the shaft g in order to give the collar s, by means oi' the cam or alm r, the desired position on the rod i with respect to the valve 7i.

The angular movement to be given to the sha'tt g and its arm r may be brought about by any suitable means, preferably with the agency ot a screw-driver. To this end the projecting end ot the sha-ft is provided with a cut a as shown in Figure 3.

It will be seen that with the aid of the described means an exact adjustment ol the valve spring m can be carried out. from the outside of the casing Without the necessity of dismounting the constituent parts oi the device.

Ihe means for setting or adjusting the thermostatic tube n is ot a construction essentially similar to that hereinbelfore described in connection with the spring m. The shaft e corresponding to the shaitt q as regards both construction and mode of operation, carries on its inner end an arm e having a slot e engaging With a pin z2 ot a short sleeve es rigidly connected with the respective end of the thermostatic tube a, Whilst the other end thereof is lirmly attached to the ring p bearing on the valve 7a..

The adjustment of the tube a may be effected in the same manner as hereinbetore described With respect to the spring adjusting means shown in Figure 3.

From the foregoing description it will be seen that simple and etlicient means are herein provided for accomplishing the objects of my invention, but While the elements shown and described are Well adapted to serve the purposes for which they are intended, it is to be understood, that the invention is not limited to the precise construction set forth, but include Within its purview such changes as may be made Within the scope of the appended claims.

What I claim, is 2- l. In a device ol" the character described, the combination with a casing, of a valve adapted to control the passage through said casing, a resilient member acting to yieldingly support said valve, a valve rod loosely carrying the valve, and a thermostatic member connected with said rod and mounted in the casing to act upon the valve in counteraction to the action of the said resilient member.
